I was recently asked about the network configuration I use for my honeyd sensor. As I now have a pretty(ish) network diagram showing my setup as a result, decided sharing is caring.
VMWare ESXi is perfect for a self contained lab, but as I’m used to having full access to a ‘real’ network there are a few things I miss not having control over for testing and other things. The biggest of these is a spanf port (or mirror port depending on your hardware). If you’re not familiar, the basic premise is to configure one (or more ports) to reproduce any traffic flowing through any port(s). This provides packet level access for debugging network problems, passing to an I[D/P]S, etc.
ESXi doesn’t provide this functionality, but does allow you to set a vSwitch to be ‘promiscuous’.
arkus keeps adding great features and functionality to Dionaea, when I read the post introducing a new web interface carniwwwhore I couldn’t help thinking I’d got lucky timing, start of a weeks vacation and no real plan for what to do with it. I’ve struggled previously with some of my Dionaea setups, largely because my system was running Debian, whilst Dionaea was built under Ubuntu; doesn’t cause too many problems, just a bit of google-fu, headscratching and stupidity that could have been avoided. From this background I looked through the carniwwwhore pre-reqs with dread, plenty of version requirements that weren’t upto date with my Debian setup; so it’s time to bite the bullet and build a fresh system with Ubuntu.
I’ve tried messing around with SSH port forwarding in the past, but always struggled to get my head around what I was trying to connect to where, and ultimately didn’t result in anything useful. This time around I’ve put in some dedicated time to get to the bottom forwarding ports within SSH tunnels. And I’m glad I did, my with only a handful of connections the possibilities are making my head spin.
Implementing the BeerWare license into DokuWiki
Mercury Live DVD was initially (I believe) announced in a post to the Nepenthes Mailing list. It is a remastered Ubuntu distribution with pre-installed honeypot applications and malware analysis tools created by John Moore.
Around a month ago Miguel Jacq got in contact to let me know about a couple of errors he encountered when running InfoSanity’s mimic-nepstats.py with a small data set. Basically if your log file did not include any submissions, or was for a period shorter than 24hours the script would crash out, not the biggest problem as most will be working with larger data sets but annoying non the less.
After first getting HoneyD up and running previously for a proof of concept I’ve begun a wider implementation of HoneyD to function as the backbone for an upgraded research environment.
HoneyD’s key strength is it’s flexibility, HoneyD’s website contains some sample configuration files that show HoneyD emulating multiple systems running different OSes and applications, a large multi-site network and even a config file to create a honeypot environment for a wireless network. I’ve found these samples immensely useful references for developing custom templates for my own implementation.
Since reading Virtual Honeypots I’ve been wanting to implement a HoneyD system, developed by Niels Provos. From it’s own site, HoneyD is a small daemon that creates virtual hosts on a network. The hosts can be configured to run arbitrary services, and their personality can be adapted so that they appear to be running certain operating systems. Honeyd enables a single host to claim multiple addresses – I have tested up to 65536 – on a LAN for network simulation. Honeyd improves cyber security by providing mechanisms for threat detection and assessment. It also deters adversaries by hiding real systems in the middle of virtual systems.
Well, the year is nearly over and it seems everyone is in a reflective mode so I thought I’d join in. And I’m glad I did, didn’t really just how turbulent year I’ve had.
